Error LED on an ACX780 controller.


  • Is the error LED on the ACX781 linked to the errors system variable in the controller?
  • What events constitute and error that would cause the LED to be illuminated?
  • How is the nature of the controller error determined?

The error led is associated with the errors system variable.


Try using Command Line to set the Errors system variable  to 0 and see if the error led goes away.

The most common reason why the error would be non-zero is because there is a program that went disabled.
